Lane Jason Kolbe Tatiana Rynearson Nasser H. Zawia DEAN OF THE GRADUATE SCHOOL UNIVERSITY OF RHODE ISLAND 2017 ABSTRACT Parasitism is a common life strategy throughout the eukaryotic tree of life. Many devastating human pathogens, including the causative agents of malaria and toxoplasmosis, have evolved from a photosynthetic ancestor. However, how an organism transitions from a photosynthetic to a parasitic life history strategy remains mostly unknown. Parasites have independently evolved dozens of times throughout the Florideophyceae (Rhodophyta), and often infect close relatives. This framework enables direct comparisons between autotrophs and parasites to investigate the early stages of parasite evolution.

Fredericq 2019. The marine macroalgae of Cabo Verde archipelago: an updated checklist. Arquipelago. Life and Marine Sciences 36: 39 - 60. An updated list of the names of the marine macroalgae of Cabo Verde, an archipelago of ten volcanic islands in the central Atlantic Ocean, is presented based on existing reports, and includes the addition of 36 species. The checklist comprises a total of 372 species names, of which 68 are brown algae (Ochrophyta), 238 are red algae (Rhodophyta) and 66 green algae (Chlorophyta). New distribution records reveal the existence of 10 putative endemic species for Cabo Verde islands, nine species that are geographically restricted to the Macaronesia, five species that are restricted to Cabo Verde islands and the nearby Tropical Western African coast, and five species known to occur only in the Maraconesian Islands and Tropical West Africa. Two species, previously considered invalid names, are here validly published as Colaconema naumannii comb. nov. and Sebdenia canariensis sp. nov.

DOI: 10.2216/09-46.1 This paper contains the first reports of Veleroa magneana in the Atlantic Ocean, Chylocladia schneideri outside of its type locality in Puerto Rico, and Verdigellas peltata and Cladocephalus luteofuscus from shallow water. Also reported are new northern limits of distribution for Chondria leptacremon, Dasya antillarum, Laurencia caraibica, Lomentaria corallicola, Myriogramme prostrata and Udotea caribaea as well as the first four mentioned. Fertile gametophytes are documented for Ptilothamnion speluncarum for the first time from the type locality. Molecular evidence shows that Halymenia pseudofloresii, a species with its type locality in Bermuda, is sister to Halymenia floresii, the generitype, in the present analysis. More critically, molecular data establish that H. pseudofloresii has a broad range of morphological variation encompassing that displayed by true H.

  • Investigating Diversity, Evolution, Development and Physiology of Red Algal Parasites from New Zealand
    Investigating diversity, evolution, development and physiology of red algal parasites from New Zealand BY MAREN PREUSS A thesis submitted to Victoria University of Wellington in fulfilment of the requirements for the degree of Doctor of Philosophy Victoria University of Wellington Te Whare Wānanga o te Ūpoko o te Ika a Māui (2018) ii This thesis was conducted under the supervision of Associate Professor Joe Zuccarello (Primary Supervisor) Victoria University of Wellington, Wellington, New Zealand and Professor Wendy Nelson (Secondary Supervisor) National Institute of Atmospheric Research, Wellington, New Zealand and University of Auckland, Auckland, New Zealand iii iv Abstract Red algal parasites have evolved independently over a 100 times and grow only on other red algal hosts. Most parasites are closely related to their host based on the similarity of their reproductive structures. Secondary pit connections between red algal parasites and their hosts are used to transfer parasite organelles and nuclei into host cells. Morphological and physiological changes in infected host cells have been observed in some species. Parasite mitochondrial genomes are similar in size and gene content to free-living red algae whereas parasite plastids are highly reduced. Overall, red algal parasites are poorly studied and thus the aim of this study was to increase the general knowledge of parasitic taxa with respect to their diversity, evolutionary origin, development, physiology, and organelle evolution. Investigation of the primary literature showed that most species descriptions of red algal parasites were poor and did not meet the criteria for defining a parasitic relationship. This literature study also revealed a lack of knowledge of many key parasitic processes including early parasite development, host cell “control”, and parasite origin.

Biodiversity Data Journal 8: e57461. https://doi.org/10.3897/BDJ.8.e57461 Abstract Background The seaweed flora of Pico Island (central group of the Azores archipelago) has attracted interest of researchers on past occasions. Despite this, the macroalgal flora of the island cannot be considered well-known as published information reflects only occasional collections. To overcome this, a thorough investigation encompassing collections and presence data recording was undertaken. Research under the Campaigns “AÇORES/89”, “PICO/91”, “PICOBEL/2007” and “LAUMACAT/2011” covered a relatively large area (approximately 39 km2 ) around the island, encompassing the littoral and sublittoral levels down to about 40 m around the Island.

Abstract—The marine benthic algae from Jarvis Island and Kingman Reef were identified from collections obtained from the Whippoor- will Expedition in 1924, the Itasca Expedition in 1935, the U.S. Coast Guard Cutter Taney in 1938, the Smithsonian Institution’s Pacific Ocean Biological Survey Program in 1964 and the U.S. National Oceanic and Atmospheric Administration’s Reef Assessment and Monitoring Program (RAMP) in 2000, 2001, 2002, 2004 and 2006. A total of 124 species, representing 8 Cyanobacteria (blue-green algae), 82 Rhodophyta (red algae), 6 Heterokontophyta (brown algae) and 28 Chlorophyta (green algae), are reported from both islands. Seventy-nine and 95 species of marine benthic algae are recorded from Jarvis Island and Kingman Reef, respectively. Of the 124 species, 77 species or 62% (4 blue-green algae, 57 red algae, 2 brown algae and 14 green algae) have never before been reported from the 11 remote reefs, atolls and low islands comprising the Line Islands in the Central Pacific. Introduction The Line Islands are located approximately 1600 kilometers south of the main Hawaiian Islands and consist of 11 remote reefs, atolls and low islands that lie between 7° N and 12° S latitude, and 150° W and 164° W longitude (Fig.
